MOTOR-TRUCK FOR CARS.

SPECIFICATION forming part of Letters Patent No. 377,122, dated January 31,1888.

(Xo model.)

To all whom, it may concern,.-

Be it known that l, HALcYoN SKINNER, of Yonkers, in the county of W'estchester and State of New York, have invented a new and useful Improvement in Motor-Trucks for Cars, of which the following is a specification.

My invention relates more particularly to means for driving or pulling street-cars.

It has been proposed to arrange a motor upon the platform of a car; but on the platform of an ordinary street-railway ear there is not sufticient room, and, again, with such an arrangement it would be necessary to provide every car which was to be used at any time with a separate motor.

My invention relates to an arrangement and combination of a motortrnck and carsueh as is shown and described in my allowed application for Letters Patent, Serial No. 227,009, led February 9, 1887. In that application I have shown and described a motor-truck which is independent of the car-truck, but connected therewith, amotor-shaft upon the motor-truck, and gearing for connecting the motor-shaft with one of the axles. In that application I have described an upper platform for the inotor-tri1ck,which is connected with the car-axle, so as to be maintained in parallelism with the car-axle when rounding curves.

According to my present invention I con neet the motor-truck, which may have but a single axle, and the car-truck or car by a reach comprising two sections, one of which may project rigidly from the motortruek and the other of which is for connection with Athe earaxle, and said reach-sections are connected together by a vert-ical p ivot to provide for their swinging one relatively to the other. The motor-shaft, which is upon the motor-truck, is geared with the car-axle, and such gearing maycomprise a transmittingshaft which is supported in bearings on the sections of the reach, and is itself composed of sections con nected by a universal coupling which is or may be concentric with the vertical pivot connecting thereachsections. The two sections ofthe reach may be constructed each with a yoke, and these two yokes may be connected by arms projecting from one yoke and pivoted to the other yoke by vertical pivots arranged one above the other. `W`hen the motor-truck has but a single axle, I provide upon the reach,

l i i and at a distance from the motor-truck, trailing wheels and swinging bearings therefor, whereby said wheels may be raised out of the way when the reach is connected with the caraxle and lowered so as to support the rear end of the reach when it is unconnected with the car-axle.

In the accompanying drawings, Figure l represents a longitudinal section, and Fig. 2 a plan, of such portions of a car and motor truck as are necessary to illustrate my invention. Fig. 3 represents a section on about the plane of the dotted line x x, Fig. 2. Figs. it and 6 represent the yolres with which the reach-seetion's are provided; and Fig. 5 is a longitudinal section through these two yokes, and also showing the arms which connect them.

Similar letters of reference designate corresponding parts in all the ligures.

A designates portions ofthe frame of an ordinary street-car, only one of the axles, B, hav ing wheels I3', being here shown; and C designates the frame of a motor-truck, which is independentfrom but connected with the car, and is, here shown, supported by butasingle axle, G', and pair of wheels C2.

I connect the motor-truck Gwith the axle B of the car by a reach which will permit the lateral movement of the motor-truck C relatively to the car A. reach consists of two sections, D D', connected together by a joint which will permit them to swing laterally, one relatively to the other,

but which will hold them securely in a vertical direction and prevent their deiection. One sect-ion, D, of the reach, which may be suit-ably constructed of metal or timber, is secured at the points d to the motor-truck C, and the other section, D', of the reach is constructed at the end with boxes or bearings d', which iit the car-axle B and are held against lateral movement thereon by collars d2. W`hen the motor is to be disconnected from one car and connected with another car, it is simply necessary to disconnect the bearings or boxes d from the axle B and to connect them with the axle of another car. Upon the motortrucl; C is a motor-shaft or crank-shaft, E, which is connected by suitable gearing with the car-axle B.

In the present example of my invention there is employed a transmitting-shaft com- As here represented, this IOO . sections D D as provided, respectively, with posed of two sections, F F', connected together by a universal joint or coupling, F2, and the section F of the transmitting shaft may be geared by a chain passing over the wheelsff' with the motor-shaft E, While the section F of the transmitting-shaft may be provided with a bevel-wheel, f2, which, by moving the transmitting-shaft 1ateraIly,-may be engaged with either of two wheels, f3 f', on the car-axle B, thereby providing, Without reversing the shaft F F', for driving the axle B in either direction. v

'Io afford provision for rounding curves, it is necessary that the two sections D D' of the reach between the motor-truck and the caraxle be connected by a vertical pivot orV pivots,which will permit their lateral deflection or swinging one relatively to the other, and will prevent their vertical deflection one relatively to the other. of my invention I have represented the reachtransverse yokes or yoked cross-bars d3 d4, one of which, d3, is provided with arms d5, connected by pivots or bolts de with the other yoke,.d. The pivots d are in line With each other vertically, and may therefore be consid,- cred as one pivot connecting the sections of the reach, and the pivots in the universal coupling orjoint F2 may be, andpreferably are, in the same vertical plane with the pivot d6. I have represented the shaft-sections F F' as su pported in bearings d7 on the reach-sections, and the section F is supported by a bearing, c,.upon the motor-truck C.

I have represented the motor-truck C as having but a single axle and pair of wheels, and therefore it is necessary to provide means for holding the motor-truck and the reach D D' in substantially horizontal position when the boxes or hearings d' are disconnected from the axle B. I have here represented a pair of trailing wheels, G, which are pivotedv upon arms g, extending from a cross-shaft, G', and this cross-shaft,which is a rock-shaft, is journaled in suitable bearings, g', upon the reachsection D'. The rock-shaft G' also has a handle arm, Gwhich by a'clamping-bolt, g2, may be secured in different positions in the aroshaped guide G3, also depending from the reachsection D'. Vlien the reachsection D is connected with a car-axle, the trailing wheels i G are, by swinging the shaft G', maintained in l In the present example y the position shown by fulllines in Fig. l and out of reach of the track-rails; but before the boxes or bearings are disconnected from the car-axle B the trailing wheels G are lowered to the position shown by dotted lines in Fig. l and to a bearing upon the track-rails.

,What I claim as my invention, and desire to secure by Letters Patent, is

1. The combination, with a car-truck and .an independent motor-truck, of a reach com- 2. The combination,with the cart-ruck and i the independent motor-truck C, of'the reach composed of the sections D D', having the rings or yokes d3 d, one of which has arms secured by vertical pivots to the other, the section D rigidly projecting from the motortruck and the section D having boxes fitting the car-axle, a motor-shaft on the motor-truck, and gearing connecting said shaft withthe car axle, substantially as herein described.

3. The combination, with a cartruck and an independent motor-truck, of a reach connecting them and 'composed of sections, onc section projecting from the motor-truck and the other being connected with the car-axle, and the two said sections being connected by a vertical pivot,and a transmitting-shaft extending from the motor-truck andgeared with the car-axle and composed of sections correspond ing to the sections of the reach and connected together by a universal joint, substantiall y as herein described.

4. The cornbination,with a motor-truck independent of a car and having a reach for connection with a car-axle, of trailing wheels'and swinging bearings therefor on the reach, whereby said wheels may be raised out of the way or lowered to support the reach when it is disconnected from a car-axle, substantiallyl as herein described.
